Keystone Studios was an early film studio founded in Edendale, California on July 4, 1912 as the Keystone Pictures Studio by Mack Sennett with backing from actor-writer Adam Kessel (1866–1946) and Charles O. Baumann (1874–1931), owners of the New York Motion Picture Company. The company, referred to at its office as The Keystone Film Company, filmed in and around Glendale and Silver Lake, Los Angeles for several years, and its films were distributed by the Mutual Film Corporation between 1912 and 1915. The Keystone film brand declined rapidly after Sennett went independent in 1917.

Edendale is a historical name for a district in Los Angeles, California, northwest of Downtown Los Angeles, in what is known today as Echo Park, Los Feliz and Silver Lake. In the opening decades of the 20th century, in the era of silent movies, Edendale was known as the home of most major movie studios on the West Coast. Among its many claims, it was home to the Keystone Cops, and the site of many movie firsts, including Charlie Chaplin's first movie, the first feature-length comedy, and the first pie-in-the-face. The Edendale movie studios were mostly concentrated in a four-block stretch of Allesandro Street, between Berkeley Avenue and Duane Street. Allesandro Street was later renamed Glendale Boulevard.
